Ports Description
10/100Base-T Fast Ethernet Ports
The 10/100Base-T Fast Ethernet ports are RJ-45. The 10/100 Mbps port supports half- and full-duplex mode.
10/100/1000Base-T Uplink Ethernet Ports
The 24/48 port devices contains two 10/100/100Base-T Gigabit ports, and the 16 port device contains one
10/100/100Base-T port. The RJ-45 1000 Mbps port supports 1000 mbps in full-duplex mode and 10/100 mbps
half- and full-duplex mode.
SFP Port
Small Form Factor Pluggable (SFP) Optical Transceivers are integrated duplex data links for bi-directional
communication over optical fiber, designed for high-speed Fiber Channel data links. The SFP port is designated
as 1000Base-FX.
DB-9 Console Port
The DB-9 port is an asynchronous serial console port supporting the RS-232 electrical specification. The port is
used to connect the device to a console managing the device. This interface configuration is as follows:
• Eight data bits.
• One stop bit.
• No parity.
• Baud rate is 115,200 (default). The user can change the rate from 115,200 down to 2400 bps.
LED Definitions
The device front panels contain Light Emitting Diodes (LED) that indicate the device status. The different LED
types are as follows:
• Port LEDs — Indicates each port status.
• Power LED — Indicates the device power supply status.
• Mode LEDs — Indicates which information the LED displays - only on non-PoE devices.
• Stacking LEDs — Indicates the device location in a stack.
Front Panel LEDs
The front panels have two types of LEDs, excluding the LEDs attached to the ports. The two types are as follows:
• Mode LEDs — Indicates which information the LED displays.
• Stacking LEDs — Indicates the device location in a stack.
